Equivalent Education may be obtained in a state accredited private school or a parochial school. According to a ruling by the U. S. Supreme Court in Pierce v Society of Sisters, states must recognize these schools as providing an education equivalent to that of the public schools so long as they follow state laws and regulations that bear a reasonable relationship to the interest the state has in educating its citizens and do not burden the religious practices of the parochial schools. These conditions placed upon non-public schools, including home schools, are permitted under the United States Constitution because the public schools must follow these regulations as well.
All non-public schools must qualify under the laws of that state as schools in order to be considered capable of providing an equivalent education. The criteria used include such factors as whether the school is established, the quality of the teaching, the soundness of the curriculum, how many hours per day are spent for instruction, how many days of the year the school is engaged in teaching, and whether the teachers are certified. A private, parochial, and home schools may have to comply with any combination of the above factors.
